Method and system for automatically generating questions for a programming language

ABSTRACT

The present invention provides a method, system and computer program product for generating a family of questions for a programming language. Generating the family of questions includes the generation of various questions from a particular compilable code, and the corresponding options for the questions. The options include various correct and incorrect options for the questions.

BACKGROUND OF THE INVENTION

The present invention relates generally to question banks. More specifically, it relates to a method and system for automatically generating questions for a programming language in the question bank.

Today, software-based organizations and educational institutions are building up comprehensive infrastructure to train and evaluate their existing employees, new recruits and students. This training plays a vital role in enhancing the technical and soft skills of employees and students, who are trained on various programming languages, which require timely assessment.

A typical question for an examinee taking an examination comprises a code that can be compiled. There are several options from which the examinee has to select the correct one. Further, the question bank contains questions in various formats such as multiple choice questions, matrix questions, etc., on which the examinee is tested.

Various formats of questions are manually created and are regularly updated in the question bank. Since the number of questions in the question bank is limited, over a period of time the examinees become aware of the questions in the question bank. Further, it becomes easy for the examinee to memorize or guess the correct options for the questions without actually solving them.

Different sets of questions may be provided to examinees who are sitting near each other to reduce the possibility of their cheating from one another. This results in a difference in the difficulty level of questions in the different sets and does not assess the examinees on the same parameters.

Furthermore, incorrect options are generated for the questions, to enable the examinees to select the correct option from a set of options provided for each question. These incorrect options are quite different from the correct options, and the examinees may be able to guess the correct options easily.

In light of the foregoing discussion, there is a need for a method for updating the question bank automatically. The method should generate and populate the question bank with an unlimited number of unique questions. Further, the method should help in reducing the time required to generate the questions. The method should also help in generating correct and incorrect options for the questions, such that examinees can be evaluated for their skills and knowledge effectively.

BRIEF SUMMARY OF THE INVENTION

An object of the invention is to generate a family of questions for a programming language.

Another object of the invention is to generate one or more questions from a particular compilable code.

Yet another object of the invention is to generate corresponding options for each question.

To achieve the objectives mentioned above, the invention provides a method, a system and a computer program product for generating a family of questions for a programming language. The family of questions includes one or more questions, which are generated from a template question. The template question includes a compilable code with one or more variables, which are defined by a user. The method enables the assignment of a first set of unique random values in the variables in the template question to generate one or more questions. Further, a plurality of options is generated that correspond to each question. Each option includes at least one correct option and at least one incorrect option for each question.

DETAILED DESCRIPTION

Various embodiments of the present invention provide a method and a system for generating a family of questions for a programming language. In various embodiments of the invention, the programming language may be C, C++, C#, JAVA, UNIX, Visual Basic, VC++, COBOL, FORTRAN, and the like. The family of questions contains various questions that are formed by using the same compilable code and the corresponding options for the questions.

FIG. 1 is a block diagram illustrating an environment 100, in which various embodiments of the invention may be practiced. Environment 100 includes a question data 102, a question generator tool 104 and a question bank 106.

Question data 102 includes various details that are required for question generator tool 104 to generate questions. Further, the questions generated by question generator tool 104 are stored in question bank 106. Question bank 106 presents the questions to examinees in various formats.

The details included in question data 102 may be a set of compliable codes, a set of pre-defined parent questions containing the compilable codes, parent questions converted to the form of a template, types of question formats, rules for generating questions, rules for generating options for the questions, the number of questions to be generated, the number of correct and incorrect options to be generated, and the like. In an embodiment of the invention, the details are provided by a user.

The various types of question formats may be multiple choice questions, matrix questions, match-the-column questions, multiple response questions, a combination thereof, and the like.

In multiple choice questions, a question with few options is provided to an examinee. The options include a correct option and various incorrect options for the compilable code present in the question. The examinee is required to select the correct option from the various options provided.

In matrix question, the compilable code of the question includes a variable in a question. Some probable values for the variable are also provided with the compilable code in the question. Further, multiple options are provided to the examinee against each value of the variable. These multiple options include a correct option and various incorrect options for each value. The examinee is required to select the correct option against each value of the variable.

In multiple response questions, the questions include more than one correct option, along with the incorrect options. The compilable code of the question includes a variable, and a specific value or a range is provided for the variable to the examinee. The examinee is required to select all the correct options possible for the value or the range of the variable.

In match-the-column questions, the compilable code of the question includes a variable. One or more values are provided to the examinee for the variable. The correct option for each value of a variable is provided in a jumbled manner to the examinee. Various incorrect options may also be provided to the examinee with the jumbled correct options. The examinee is required to match the correct options against each value of the variable.

Question generator tool 104 utilizes the details provided by question data 102 to generate a family of questions for a programming language.

The family of questions includes various questions and their corresponding options. These questions are derived from a compilable code. The following is an exemplary compilable code written in C to generate a family of questions:

# include <stdio.h>  main ( )  {     int iNum;   for(iNum=0;iNum<45;iNum++);   printf(“%d”,iNum);   }

Question generator tool 104 automatically generates the family of questions by changing certain values in the compilable code. For example, to form a question, the maximum value of iNum in the code mentioned above can be changed from 45 to 50. Similarly, other questions can be derived from the compilable code, which further changes the value of iNum. In an embodiment of the invention, the parameters for which the values may be modified to generate the questions are defined by a user. In another embodiment of the invention, the parameters for which the values can be modified to generate the questions are dynamically selected by question generator tool 104. In addition to generating questions, question generator tool 104 generates options that correspond to the questions. These options include the correct and incorrect options for the question. The generation of options is explained in detail in conjunction with FIG. 3.

The questions and the corresponding options generated by question generator tool 104 are stored in question bank 106. In an embodiment of the invention, question bank 106 provides questions for an online examination. In another embodiment of the invention, question bank 106 provides questions that can be printed on paper.

FIG. 2 is a flowchart illustrating a method for generating the family of questions for a programming language, in accordance with an embodiment of the invention. In various embodiments of the invention, the programming languages may be C, C++, C#, JAVA, UNIX, Visual Basic, VC++, COBOL, FORTRAN, and the like.

The family of questions includes questions and corresponding options for each question. The questions are derived from a pre-defined parent question. The pre-defined parent question also contains a compilable code. The pre-defined parent question is converted to a template question by inserting a variable in the pre-defined parent question. The generation of the template question from the pre-defined parent question is explained in detail in conjunction with FIG. 3.

At 202, a first set of unique random values are assigned to the variable in the template question, to generate the questions. In various embodiments of the invention, the type of variable may be defined as an integer, a floating point, a double floating point, an alphanumeric, and the like.

In an embodiment of the invention, the first set of unique random values may be generated automatically. In another embodiment of the invention, the first set of unique random values may be provided by a user.

At 204, various options are generated for the questions generated at 202. Various options include a correct option and different incorrect options for the compilable code of the questions. In an embodiment of the invention, the correct question may have more than one option for the compilable code. The generation of the correct and incorrect options is explained in detail in conjunction with FIG. 3. The questions, along with their corresponding options, are considered to be a family of questions.

FIG. 3 is a flowchart illustrating a method for generating the family of questions for a programming language, in accordance with another embodiment of the invention. The family of questions includes various questions and the options for each question. The options include the correct and incorrect options for the questions that correspond to the compilation of the compilable code in the question.

At 302, a template question is created. The template question is derived from a pre-defined parent question, which comprises a compilable code.

In an exemplary embodiment of the invention, the pre-defined parent question containing the compilable code is the following:

#include<stdio.h> main( ) { int iNum=10,iResult=0; iResult=iNum++; printf(“%d”,iNum++);          }

The pre-defined parent question is converted to a template question by inserting a variable in the pre-defined parent question. In an embodiment of the invention, the variable in the template question is defined by a user.

For example, the template question derived from the pre-defined parent question mentioned above may be

#include<stdio.h> main( ) { int iNum=$,iResult=0; iResult=iNum++; printf(“%d”,iNum++);          }

where $1 is the variable. In various embodiments of the invention, the type of variable may be defined as an integer, a floating point, a double floating point, an alphanumeric, and the like.

In an embodiment of the invention, more than one variable may be inserted in the pre-defined parent question.

At 304, a misinterpretation template is created. In an embodiment of the invention, the misinterpretation template is created by a user. The misinterpretation template is derived from the template question and contains the misinterpretation code. The misinterpretation code is a wrong interpretation of the compilable code contained in the template question. For example, if the compilable code is

#include<stdio.h> main( ) { int iNum=2,iResult=0; iResult=iNum++; printf(“%d”,iNum++);          }

the correct output of this compilable code is 2. However, an examinee taking an examination may interpret the compilable code incorrectly and consider the output to be 3. Hence, the misinterpretation code for this type of misinterpretation is the following:

#include<stdio.h> main( ) { int iNum=2,iResult=0; iResult=++iNum; printf(“%d”,++iNum);          }

In an embodiment of the invention, more than one misinterpretation template may be provided for each template question.

At 306, a first set of unique random values is generated for the variables in the template question, in accordance with a range defined for the variable. In an embodiment of the invention, the range for the variable is defined by a user. The first set of unique random values is used to generate the questions. In another embodiment of the invention, the first set of unique random values is generated automatically. In yet another embodiment of the invention, the first set of unique random values is provided by the user.

At 308, a second set of unique random values (k_(i)) is generated, in accordance with a tolerance range defined for the incorrect options. In an embodiment of the invention, the tolerance range is defined by a user. The second set of unique random values is used to generate the incorrect options for the questions. In another embodiment of the invention, the second set of unique random values is generated automatically. In yet another embodiment of the invention, the second set of unique random values is provided by the user.

At 310, a random value from the first set of unique random values is assigned to the variable in the template question, to generate a question. In an embodiment of the invention, the random values from the first set are assigned sequentially to generate various questions from the template question. In another embodiment of the invention, the random values are selected randomly from the first set. In various embodiments of the invention, a pre-defined number of questions may be generated by assigning the random values to the variable in the template question. Each random value from the first set of random values is used only once while generating the pre-defined number of questions.

At 312, a tag is assigned to the question generated at 310. Similarly, different tags are assigned to the pre-defined number of questions generated at 310. The tag assigned to the question is used to identify the question.

In various embodiments the question generated after the first set of unique random values are assigned, are stored in a particular format. An example of the format may be, but is not limited to, the, a tagged format, an XML tagged format, a Question Markup Language (QML) format, a Flat File format, and a database.

At 314, the question generated at 310 is compiled to generate an output. This compilation includes compiling the compilable code contained in the question. The output is stored as the correct option for the question. In an embodiment of the invention, the correct output is temporarily stored in a cache memory.

At 316, a tag is assigned to the correct option. This tag is used to identify the correct option. In an embodiment of the invention, the tag is assigned to the correct option that is stored temporarily in a cache memory.

In various embodiments of the invention, the correct option generated after compiling the compilable code contained in the question, are stored in a particular format. An example of the format may be, but is not limited to, the, a tagged format, an XML tagged format, a QML format, a Flat File format, and a database.

At 318, the random value from the first set of unique random values assigned at 310 is assigned to the variable in the misinterpretation template, to form a misinterpreted question. In an embodiment of the invention, the random values from the first set are assigned sequentially to generate various misinterpreted questions from the template question. In another embodiment of the invention, the random values from the first set are selected randomly. In various embodiments of the invention, the pre-defined number of misinterpreted questions may be generated by assigning the random values to the variable in the misinterpretation template. Each random value from the first set of random values is used only once while generating the pre-defined number of misinterpreted questions.

In various embodiments of the invention, the misinterpreted question generated after the first set of unique random values are assigned, along with the misinterpreted code, are stored in a particular format. An example of the format may be, but is not limited to, the, a tagged format, an XML tagged format, a QML format, a Flat File format, and a database.

At 320, the misinterpretation code in the misinterpreted question is compiled to generate an output. This output is stored as the first incorrect option for the question generated at 310. In an embodiment of the invention, the first incorrect option is stored temporarily in a cache memory.

In an embodiment of the invention, more than one misinterpretation template may be created for each question at 304. This results in more than one first incorrect option for the question.

At 322, a tag is assigned to the first incorrect option. This tag is used to identify the first incorrect option. In an embodiment of the invention, the tag is assigned to the first incorrect option that is temporarily stored in a cache memory.

In various embodiments of the invention, the first incorrect option generated after compiling the misinterpretation code in the misinterpreted question, is stored in a particular format. An example of the format may be, but is not limited to, the, a tagged format, an XML tagged format, a QML format, a Flat File format, and a database.

In an embodiment of the invention, different tags may be associated with more than one first incorrect option generated by more than one misinterpretation template.

At 324, a second incorrect option is generated by using a random value from the second set of unique random values (k_(i)) and the correct option generated at 314. In an embodiment of the invention, the second incorrect option generated is stored temporarily in a cache memory.

In an embodiment of the invention, the second incorrect option is calculated by the following formula Second Incorrect Option=Correct Option (+−)k_(i)*α*(correct option)

where α is a value of the tolerance limit. In an embodiment of the invention, the tolerance limit may be defined by a user. In an alternative embodiment of the invention, the tolerance limit may be taken as an input from a user in real time. The values of the tolerance limit may be 1%, 2%, 3%, 4%, and the like. For example, if the correct option corresponding to the question generated at 310 is 2, one of the incorrect options corresponding to the question would be 4, i.e., 2+30*4%*2. Here the value of k_(i) has been considered as 30 and α as 4%. Similarly, another incorrect option would be 0, i.e., 2−30*4% 2. Further, various other incorrect options can be generated by the second set of unique random values (k_(i)), the tolerance limit value (a) and the correct option.

In an embodiment of the invention, the number of incorrect options to be generated may be defined by a user.

At 326, a tag is assigned to the second incorrect option. The tag associated with the second incorrect option is used to identify the second incorrect option. In an embodiment of the invention, the tag is assigned to the second incorrect option that is stored temporarily in a cache memory.

In various embodiments of the invention, the second incorrect option is stored in a particular format. An example of the format may be, but is not limited to, the, a tagged format, an XML tagged format, a QML format a Flat File format, and a database.

In another embodiment of the invention, different tags may be associated with the incorrect options generated by the formula mentioned above.

At 328, the question, the correct option, the first incorrect option and the second incorrect option are stored in a file with their corresponding tags.

In various embodiments of the invention, the question, the correct option, the first incorrect option and the second incorrect option, are stored in a particular format. An example of the format may be, but is not limited to, the, a tagged format, an XML tagged format, a Question Markup Language (QML) format, a Flat File format, and a database.

In another embodiment of the invention, the tags associated with the options are randomly stored against each question.

Similarly, various questions, with their corresponding options, are generated from the template question. These questions, with their corresponding options, are considered to be a family of questions.

In another embodiment of the invention, various incorrect options for each question may be generated only by compiling the misinterpretation codes in the one or more misinterpretation templates. Similarly, various incorrect options may be generated only by the second set of unique random values and the correct option for each question.

In yet another embodiment of the invention, it is ensured that the random values used to generate options are not repeated during a period of time.

In an alternative embodiment of the invention, all the random values present in the first set of random values are assigned to the template question, to generate multiple questions at one instance. These questions are later complied to generate their corresponding options.
